Features

The FCV-2100 is a color fish finder with split-beam technology for estimating fish sizes. The system is comprised of a Trackball Control Unit, Processor Unit, Transceiver Unit and Transducer. The FCV-2100 shows echoes on a monitor (local supply).

The main features of the FCV-2100 are:

• Wide-band technology allows the display of high-resolution fish echoes.

• Fish-size graph allows estimation of fish distribution at a glance.

• Target location graph allows tracking of a designated fish target.

• Hardness graph allows monitoring of the seabed hardness.

• Data recording and screen-shot function allow easy review of past echoes and recordings.

• Scroll-back mode allows the user to review past data.

• Gain changes made at the FCV-2100 are applied to all screens currently displayed on the FCV2100 (excludes external fish finders).

• Recorded data can be saved to an external recording device.

• Display up to three separate echo images; available with the connection of an externally networked fish finder (external fish finder), such as DFF3/DFF1-UHD.

• Constant stable display of echoes is achievable with the use of the heave offset function (re-

quires connection to a SATELLITE COMPASS

™

• Location of fish schools can be output to connected navigational equipment.

EX GAIN HF] indication.

For low frequency, this indication appears as [EX GAIN LF

Depending on the signal strength, gain can be adjusted to hide noise and other unnecessary echoes. A high gain setting increases signal strength and can show excessive noise as well as smaller, hard to detect echoes. A low gain setting eliminates noise and gives a clearer picture, however smaller echoes may also be removed.

CAUTION

Adjust the gain properly.

Too little gain may present no picture. Too much gain shows excessive noise on the picture.

1.20.2 How to use the ACCU-FISH

The ACCU-FISH™ feature requires connection to a compatible transducer.

™

feature

The ACCU-FISH

™

feature outputs fish echoes with a mark and an estimated size.

Important considerations when using the ACCU-FISH™ feature

• The ACCU-FISH™ feature is intended for reference purposes; it is not a completely accurate measurement of fish length.

• Echo intensity depends on fish species. When the fish length differs between the indicated length and the actual length, you can compensate the difference on the [Calibration] menu (see section 4.8.4).

• Fish at depths of less than two meters cannot be measured. However, if [Zero Line Rejector] is set to [On], fish within the area covered by the transmission line cannot be detected.

• The maximum depth at which the ACCU-FISH

™

feature can detect fish varies, depending on transducer type, vessel configuration, sea conditions and other factors which may affect beam accuracy.

• In a school of fish, the echoes overlap. This causes a greater margin of error in fish size measurement.

• This feature cannot be used with inside-hull transducers. Depending on the transducer frequency, fish may not be detected. Further, even if fish are detected, their indicated length may be smaller than the actual length.

• The TX pulse length changes according to ACCU-FISH

™

On/Off state. This causes

a difference in both sensitivity and the echoes viewed.

How to activate/deactivate the ACCU-FISH™ feature

1. Place the cursor inside the external fish finder screen, then right-click. The [Exter-

nal Fish Finder] menu appears.

1.26 How to Adjust TVG (Time Varied Gain)

A school of fish at a deep depth is displayed in weak colors even if it is equal in strength to one in shallow waters. This is due to propagation attenuation of the ultrasonic wave. To compensate for this difference, use TVG. TVG automatically adjusts the gain with depth so that echoes of the same strength and different depths are shown in the same colors regardless of their depths. The gain is increased with depth to display echoes of equal strengths in the same colors. In the figure below, for example, the TVG is set for 100 m and the TVG level is adjusted. Then, unwanted echoes at a distance less than 100 m are deleted and echoes at depths greater than 100 m are not affected.

2.2.8 How to calibrate the target echo strength

To accurately analyze fish distribution, it is necessary to calibrate target strength using a calibration sphere with a diameter of at least 38.1 mm. The calibration is done to match the target strength value displayed in the fish histogram dialog box with the target strength value of the calibration sphere.

To calibrate the target strength, do the following:

1. Suspend a calibration sphere at least 3 m below the transducer.

2. Set the measurement mode to [Specific Area] (see section 2.2.2).

3. Adjust the area marker (colored rectangle, see section 2.2.6) to place the calibration sphere echo inside the measurement area. Keep the measurement area small, to avoid unwanted echoes.

4. Check the fish size displayed on the graph in comparison to the calibration sphere. Note that calibration can be completed if there are other echoes present.

5. Confirm that the calibration sphere echo appears inside the area marker in consecutive scans before proceeding to the next step.

6. Select the [Advance Settings] icon ( ) from the InstantAccess bar™.

7. Select the [Advanced Settings] icon ( ) from the Menu bar. The [Advanced

Settings] menu is displayed.

Menu item Description

[Sound Speed] Adjust the sound velocity of the TX/RX signal if the depth indication is

incorrect, often caused by water temperature or salinity.

[Temperature] If the water temperature indication is wrong, you can correct it here.

For example, if the actual temperature is 2°C higher than the temperature displayed on screen, set the offset to [+2°C].

[Bottom Level] In the default bottom level setting [0], the equipment judges consecu-

tive strong echoes to be bottom echoes. If, in that setting, the depth indication is unstable, adjust the bottom level. If vertical lines extend upward from the bottom echo in the bottom lock display, lower the bottom level to erase the vertical lines. If the level is too low, however, it may be difficult to distinguish bottom fish from the bottom echo.

[Position to Start Bottom

Set the depth threshold at which the seabed is detected.

Detection] [Zero Line Rejector] Turn the zero line (transmission line) on or off. When turned on, the

transmission line disappears, which allows you to see fish echoes near the surface clearly. The length of the transmission line changes with transducer used and installation characteristics.

[Zero Line Area] This function adjusts the transmission line so that the transmission line

disappears when the menu item [Zero Line Rejection] is turned on. For a long tail, increase the value. If the transmission line does not disap-

pear, lower the TX power. [Zero Line Fill] Turn off to see fish echoes within 1 m from the surface. [Draft] The default depth display shows the distance from the transducer. If

you would rather show the distance from the sea surface, set your

ship's draft. The draft line for HF and LF can be set respectively. [Gain ADJ] If the gain is too high or too low, or the gain for the low and high fre-

quencies appears unbalanced, you can compensate it here. [Fish Size] Compensate for incorrect fish size indications. A positive value in-

creases compensation, a negative value decreases compensation.

For example [+50] increases the size indication by 1.5 times. [Calibration Setting] Set the target strength (echo strength for individual fish). If a calibra-

tion sphere was used, its value is shown. This value may be fine tuned.

For further details, see section 2.2.8.

The larger the calibration figure the longer the length of the individual

fish, even if the received signal is the same strength.

TX/RX menu

The [TX/RX] menu contains settings for pulse transmission and receipt. Depending on your vessel’s configuration, some menu items may not be available. See the lists below for more details.

Menu item Description

[TX Power] Adjusts the output power of the transducer. Where fish finders or

other equipment causes interference, you can adjust the output power level to help reduce, or eliminate, the interference. You can also disable transmission completely by selecting the [Off] option. The setting options are different for DFF3 and DFF1-UHD:

DFF3: [Off], [1] to [10] DFF1-UHD: [Auto]*, [Off], [MIN] (Minimum), [MAX] (Maximum)

*: Select [Auto] to automatically adjust the transmission power, which produces higher quality seabed echoes.

[TX Rate] Adjusts the transmission rate for the transducer. When in shallow

waters second reflection echoes may appear between the surface and actual bottom echo. In this case, lower the TX rate level. Use a high rate for fast speed; a slow rate for slow speed.

Menu item Description

[TX Pulse] Pulse width changes according to range and shift values. However,

when long range detection or better resolution is your objective, you can manually adjust the pulse width. the available settings are:

• [1/4]: Higher resolution, however range is lower than the [1/2] setting.

• [1/2]: High resolution, however range is lower then the [Std] setting.

• [Std]: Standard (default) setting. Range and resolution are balanced.

• [×2]: Higher range than [Std], however resolution is lower.

• [Manual]: Adjust the pulse width manually.

[Pulse Length] Available only when [TX Pulse] is set to [Manual]. A low setting

gives a higher resolution, however the range is lowered. A high setting give a longer range, however the resolution is lowered.

[RX Band] Rx bandwidth is automatically set according to [TX Pulse] → [Pulse

Length].The [Normal] setting provides good performance. If noise is a problem switch to [Narrow]. For better resolution, select [Wide]. [Manual] enables manual setting of Rx band width, at [RX Band Width].

[RX Band Width] Operative when [Manual] is selected at [RX Band]. A small value

decreases the noise. On the other hand, a large value gives better resolution.

Menu item Description

[Zero Line Rejection]

Turn the zero line (transmission line) on or off. When turned [On], the transmission line disappears, which allows you to see fish echoes near the surface clearly. The width of the transmission line changes with transducer used and installation characteristics.

[Zero Line Area] Adjust the transmission line so that the transmission line disap-

pears when the [Zero Line Rejector] is turned on. For a long tail, increase the value. If the transmission line does not disappear, lower the TX power.

[Draft] The default depth display shows the distance from the transducer.

If you would rather show the distance from the sea surface, set your ship's draft. The draft line for HF and LF can be set respectively.

[Fish Size] Compensate for incorrect fish size indications. A positive value in-

creases compensation, a negative value decreases compensation. For example [+50] increases the size indication by 1.5 times.

[Sound Speed] Adjust the sound velocity of the TX/RX signal if the depth indication

is incorrect, often caused by water temperature or salinity.

Calibration

Menu item Description

[Bottom Level] In the default bottom level setting [0], the equipment judges con-

secutive strong echoes to be bottom echoes. If, in that setting, the depth indication is unstable, adjust the bottom level. If vertical lines extend upward from the bottom echo in the bottom lock display, lower the bottom level to erase the vertical lines. If the level is too low, however, it may be difficult to distinguish bottom fish from the bottom echo.

[Gain ADJ] If the gain is too high or too low, or the gain for the low and high

frequencies appears unbalanced, you can compensate it here.
